b all whom it may concern: I

Be it known. that 1.,ARTHUR Gnome "Wrrr, oi the city of Hamilton, in the county ct Weutworth, in the Province of @ntario, Canada, have invented certain new and use ful improvements in Shock'libsorbers, of which the following is the specification. 1

My invention relates to improvements in shock absorbers and the object of the invention is to devise a shock absorber adaptable to automobiles, motorcycles, bicycles and other vehicles and which will have a pneumatic cushion eilect thereby gradually absorbing the shock and at the same time provide means which will eliminate the clan ger of blow-out in the cushion of the ab sol-her and it consists essentially of the fol lowing :u'rcngement and construction of parts as hereinafter inore particularly ere plaincd Figure l is a general perspective view of my absorber.

Fig. i) is vertical section through Fig. 1.

Fig. 3 is a detail. of my ball cushion,

in the drawings like letters of reference indicate cm'responding parts in the variol'ls figures.

1 indicates the absorber casing comprising an upper cylindrical member 2 having an open lower end into which telescopically fits a lower cylindrical member 3. The member 3 is provided with vertical sloth i; and 5. 6 and T indicate screws which extend through 'lho upper cylindrical member 2 in proximity to its lower edge, the screws 6 and '1 being provided at their inner ends with pin extensions 6" and 7 fitting into the slots -l and 5.

8 indicates a circular plate which rests upon the upper edge of the lower cylindrical member 3 within the upper cylindrical member 2.

9 and. 10 indicate cup rings, which fit in the upper cylindrical member the cup ring 10 lilting at the upper end of the cylindrical member 2 and the lower cup ring 9 resting upon the plate 8.

11' indicates a ball cushion which is pref crably in the form of hollow rubber having an outer reinforcement of canvas 1 and is similar to the construction employed in tennis balls. he cushion. ball 11 is inserted within the upper cylindrical meiiober 2 her tween the plate 8 and cup ring member and the upper end of the cylindrical member and the cup ring member 10.

12 and 13 indicate brackets by which the shock absorber is connected respectively to the opposing; members of a vehicle, S1181 as the axle and body of the vehicle, the bracket -12 being connected by a rivet 14 to the lower eild of the member 3 and the bracket 13 hemp: connected by a rivet 15 to theupper end oil the member 2.

It will thus be seen that when a shock occurs upon the vehicle that the members 2 and 3 will have a tendency to telescope one within the other thereby compressing the cushion ball which absorbs the shock, the walls of the ball of the cushion as they are forced outwardly by compression bearing upon the inner faces of the cap rings 9 and 10 forming a supporting bearing for .the wall of the ball preventing any tendency of its blowing out;

During this movement the parts are held Patented. Aug 261 l91&

together by the pins 6 and 7* extending into the slots l and 5 preventing the members 3 and 2 separating apart when they are separated to their fullest extent.

If desired the cushion rings 9 and 10 may be dispensed with the plate 8 being made curved to correspond to the shape of the rings and the upper portion of the casing thickened at the top corner to correspond to the shape of the upper ring 10. A suitable valve and flexible connection may also be provided such as shown at 16 for supplying air to the ball. 11.

From this description it will be seen that l have devised a very simpleform of shock absorber which will-gradually absorb any shock, which is simple and cheap in construction; and in which there will be no tendency to blow out.

What l. claim as my invention is:

1. A shock absorber comprising upper and lower cylindrical members adapted to be secured to the opposing portions of a vehicle and telescoping one Within the other,

a plate resting upon the upper edge of the lower telescoping member, a ball cushion inserted in the upper telescoping member and resting upon the plate, and opposing cup ring members, one member being held in the upper end of the upper telescoping member and the other cup fir- H'LQIYLEFO? carried by the pi'aia the opposlte side of the ball cushion.

A shock absorber compriaing an upper cylindrical mmber and a lower cylinG-ricui member having vertical slots and ailapted to be secured to thgopposhw pmrtisms of a vehicle and telescoping one "\L 11111 Lhe. other, a pneumatic cushion inserted behveen the telescoping m nbcrs, and screw msmbers 1w 3.0
